Hitting the right wrong note

Alan Rusbridger (Facing the music, 12 January) quotes Murray Perahia on the question of mistakes. I remember András Schiff as a young man being challenged in an interview about mistakes he had allowed to remain in his recordings. He replied (thoughtfully, after a long pause): "I believe there is such a thing as a wrong wrong note and a right wrong note."Catherine Boswell FriedLondon

• Regarding David McKie's article (Oh, to live in Iglesias Street, 17 January), last week, walking from Paddington to Euston Station, I chanced on "Joe Strummer Subway", just off the Westway. Apparently it's where Joe busked in his pre-Clash days. As McKie says, "occasionally a hero of the people is honoured".Dave ThriftChester

• Your editorial (In praise of… Leeds, ville française, 18 January) missed one of Leeds's most notable French residents. Louis Le Prince, the "father of cinematography", conducted his pioneering film work in Leeds in the 1880s, including his famous film of Leeds Bridge.Andrew McKeonOtley

• Formica reminiscences (Shiny, happy households, G2, 17 January)? The tables in the Kardomah coffee shops were Formica-covered in the 50s, and the one in Swansea is still going strong exactly as it was then! Coffee good too. Starbucks and Caffè Nero eat your heart out!Maggie LeeExmouth, Devon
